Two Transformers: Age of Extinction Behind-The-Scenes Featurettes

Earlier this year, we showed you several videos and photos from the Detroit set of Transformers: Age of Extinction, which teased some of the intense action of this highly-anticipated sequel. Today, we have two videos from Entertainment Tonight's visit to the set, both in Detroit and Hong Kong, featuring explosive footage and interviews with Mark Wahlberg, Jack Reynor, Nicola Peltz, along with some of the new cars being featured in director Michael Bay's action-thriller. Find out more about one of next summer's biggest movie events, including what kinds of pranks were pulled on the set.
